My 12 year old would like to invite two schoolfriends round but doesn’t want to do the kind of things he’d have been quite happy doing a year or two ago. So Lego, the natural history museum or going to the pool aren’t going to cut it. I’m at a loss. We are in south London and don’t have a car so it’s public transport. Has anyone else been in this situation and found pre teen friendly activities? Any suggestions gratefully received.
